# 函数：dvpp_get_channel_desc_channel_id

| C函数原型 | uint64\_t acldvppGetChannelDescChannelId(const acldvppChannelDesc \*channelDesc) |
| --- | --- |
| Python函数 | channel\_id = acl.media. dvpp\_get\_channel\_desc\_channel\_id (dvpp\_channel\_desc) |
| 函数功能 | 根据通道描述信息获取通道ID。同步接口。 |
| 输入说明 | dvpp\_channel\_desc：int，指定通道描述信息。 调用acl.media.dvpp\_create\_channel\_desc接口创建的dvpp\_channel\_desc数据。 |
| 返回值说明 | channel\_id：int，返回通道ID。 |
| 约束说明 | 接口调用顺序：acl.media.dvpp\_create\_channel\_desc \-\-> acl.media.dvpp\_create\_channel\-\-> acl.media.dvpp\_get\_channel\_desc\_channel\_id。 |
